What it does

Items Sheet Sprites is an agent skill from webdevcody/survive-the-night-game. Add or regenerate 16×16 item/resource icons on items-sheet.png (Pillow), align with game-shared asset coords, InteractableTexts, and optional interactableDisplayName. Use when adding new pickup sprites, patching the items atlas, or fixing misaligned tiles.

Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The licence is MIT.

6 steps, taken from the first numbered list in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit 2bbd1ab. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- python3
- pip
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Items Sheet Sprites loads about 974 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 402 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~69
When it runs · the whole SKILL.md, loaded when a task matches: ~974

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: items-sheet-sprites
description: Add or regenerate 16×16 item/resource icons on items-sheet.png (Pillow), align with game-shared asset coords, InteractableTexts, and optional interactableDisplayName. Use when adding new pickup sprites, patching the items atlas, or fixing misaligned tiles.

Items sheet sprites (16×16)

Context

Atlas file: packages/website/public/sheets/items-sheet.png — loaded by the client as /sheets/items-sheet.png (see packages/game-client/src/managers/asset.ts).
Tile size: 16×16 pixels per icon (matches world-config.TILE_SIZE).
Config: Each item/resource uses assets: { assetKey, x, y, sheet: "items" } in ITEM_CONFIGS / RESOURCE_CONFIGS. x and y are top-left pixel coordinates on the sheet, on a 16px grid (multiples of 16).

Grid rules (avoid broken UVs)

The sheet width is commonly 160px → 10 columns; valid x positions are 0, 16, …, 144. Do not use x ≥ 160 for a 160px-wide sheet (the rightmost16×16 cell starts at x = 144).
If you need a new row, extend the PNG height by 16 (or more) and place the tile at (column * 16, newRowY).
After resizing the sheet, ensure no other configs still assume an old height (search for y: values in shared entity configs).

Recommended workflow: patch script

The repo maintains a reproducible painter:

Open scripts/patch-items-sheet-sprites.py.
Add a spr_your_item() function that returns a RGBA Image of size (16, 16) (use Image.new("RGBA", (16, 16), (0,0,0,0)) and ImageDraw / pixel loops). Reuse palette constants at the top of the file for visual consistency.
Append (pixelX, pixelY, spr_your_item) to the PATCHES list.
If the new pixelY (plus16) exceeds the sheet height the script uses, update main() so nh (new height) is at least pixelY + 16 (the script already does max(oh, 224) — raise the floor or compute max(oh, max_y + 16) for all patches).
Run from repo root with Pillow available:

bash

python3 -m venv .venv-sprite
./.venv-sprite/bin/pip install pillow
./.venv-sprite/bin/python3 scripts/patch-items-sheet-sprites.py

Commit the updated PNG and script. Remove .venv-sprite if you do not want a local venv in the tree (add .venv-sprite/ to .gitignore if you keep regenerating).

Alternative: one-off Pillow script that opens the sheet, pastes a 16×16 tile at (x, y), and saves — same rules; prefer extending patch-items-sheet-sprites.py so art stays reproducible.

Wire-up after the pixel lands

Set assets.x / assets.y / assets.assetKey on the item or resource config to match the pasted cell.
Pickup / Interactive encoding: Generic entities use interactableDisplayName (see BehaviorConfigs) or derive id with underscores → spaces. That string must exist in InteractableTexts (append at the end only — wire ids are declaration order).

scripts/patch-crafting-station-sprites.py — environment tiles on the same sheet (e.g. row y = 224).

Example: zombie skin

zombie_skin was placed on a new row at (0, 240) after extending the sheet to 256px tall, with coords updated in RESOURCE_CONFIGS. New icons should follow the same pattern if the sheet runs out of empty cells on existing rows.
